Write and read data in the caches

Hi all,
I would like to test the Zynq cache memories (L1 I/D and L2).
Basically, I want to write data into one of the caches and then I want to read back the written data.

My question is: is it possible to perform this? If yes, which is the way to implement this?

Since now, thank you very much for the attention.

Thank you for the reply Gary.

I already checked this wiki.

My doubt now is how to ensure that the data are in the cache. Do you know?

Do you know if the use of the function Xil_SetTlbAttributes ensure this?

Thank you!

If the mmu is enabled, the propper use of Xil_SetTlbAttributes should ensure this.
Herefor you can read this:

Maybe you can use the PMU to check it.
